Both seemed to place blame on Clinton's top State Department aide and attorney Cheryl Mills.

Meghan McCain reacted by saying that Clinton has made poor choices when it comes to picking her closest advisers. But Julie Roginsky, formerly a senior political strategist for Democratic Senator Frank Lautenberg, said Clinton had an "incredible staff" when she was in the Senate and picks "good people."

McCain called that "ridiculous," arguing that Clinton has long been getting bad advice from a team made up of "yes-men and enablers."

"Look what they helped get her into," she added, wondering whether Clinton is surrounded by people who simply "kiss [her] you-know-what."

Guy Benson agreed, but lamented the idea that - if recent polls are correct - Clinton will end up getting away with what she did, as Tanden wrote in the email.

"Hillary Clinton at the moment looks like she's poised to win. That's the demoralizing reality. She probably is going to get away with this," he said.
